  You are using Microsoft's implementation of scanf(), (because that is all
 that MinGW has ever used for this function, and its siblings), so the
 behaviour is as Microsoft have specified it, (and there appears to be
 nothing in their documentation to suggest how infinities and nans might be
 converted,
 [...]
 You may consider Microsoft's implementation to be broken -- and you may
 well be right -- but good luck with trying to get them to acknowledge
 that, much less fix it.
